Village-based biological control of fall armyworm in Zambia

Fall Armyworms, is one of the most damaging invasive species in Zambia, if left unchecked, can result in low food production and insecurity. In particular, the pest affects the country’s key staple food maize.

It is estimated that 98% of smallholder farmers are affected by fall Armyworms every season resulting in an economic loss in the country of about US$159 million.

This backdrop provides a premise for the inception of a new project dubbed “Village-based Biological control of Fall Armyworm in Zambia,” funded by the Australian government (CIAR) and spearheaded by CABI.

Speaking during the official launch of the project, CABI Project Scientist Lena Durocher-Granger disclosed that the new project will focus on research and also reach out to 5,000 farmers on knowledge generated on low risk solutions developed during the project lifespan, noting that knowledge transfer will be key to help farmers make informed decisions on how best to address fall armyworm.

Ministry of Agriculture Permanent Secretary Green Mbozi says fall armyworm has caused enormous damage to the country’s staple food maize, prompting Government to spend a lot of funds to curb the spread of fall armyworm.

Mr Mbozi explained that the management of fall armyworm is mostly dependent on the use of conventional chemical pesticides, which utilises a field-by-field approach. Currently, nearly 43% of farmers use pesticides every season of which 9% use highly hazardous pesticides, some of which are listed in the Rotterdam convention.

“The excessive use of pesticides impacts on food quality, the natural environment, farming communities’ health and food safety and can lead to insecticide resistance,” Mr Mbozi said.

Zambia Agricultural Research Institute Director Ivor Mukuka said non-chemical practices are posed to effectively contribute to the Integrated Pest Management (IPM). Sadly, they are not adopted widely. This is particularly evident in developing countries, where there is lack of coordinated actions among community members. This situation has led to poor adoption levels of IPM. Coupled with that there are few biopesticides for fall armyworm registered in Zambia. Unfortunately, the few registered are unknown to farmers.

The University of Zambia Dean of School of Agricultural Sciences Thomson Kalinde observed that the inception of the project will endeavour to tackle the FAW, which has previously seen farmers rely on synthetic pesticides which has not been effective.

“This project is well posed to achieve good results with strong collaboration with partners engaged in research interventions which provide low risk solutions aimed at addressing fall armyworm, which has been a menace for a long time,” Prof Kalinde said.

CABI Regional Representative Southern Africa Noah Phiri explained that over the years, CABI has been working with key partners such as ZARI, GIZ, among others in executing some of its research interventions and knowledge sharing.

Dr Phiri pointed out that CABI and its partners need to seriously address the availability of technologies, which is premised on its mandate of delivering nature based solutions for management of fall armyworms.

“There is need to look at making technologies available and affordable,” said Dr Phiri.

He also mentioned that a number of trainings have been conducted as part of creating awareness on these non-chemical remedies.

How to kill rats in your poultry house - using a mixture of baking soda, flour and sugar

Rats are dangerous animals in the poultry house and they cause problems both direct and indirect. Direct - they eat chicks or kill chicks rapidly. Indirect - they carry many diseases that affect chicks. Therefore, their presence in the poultry house is a big risk. However, it is a bit hard to control rats in the poultry house because most of the chemicals that kill rats are harmful to our birds. Nevertheless, today we shall break the secret on how to kill rats using safe methods. Remember I am an organic poultry farmer and I promote organic methods all the time. So now, let us see how to solve this rat issue. Organic method of getting rid of rats on farms and at home: Mix baking soda + flour + sugar at equal ratios 1:1:1. Mix thoroughly dry. Put them in small containers and place them at the corners of your poultry house. They will eat it and never return to disturb you again. If you have a small bowl of that size, you can also use it. Rats love flour and so will golf it. Secondly, t

Hilling potatoes: why it is important

The main reason to hill potatoes is to increase yield. Potatoes form along the underground stem of the plant and not from the roots. So hilling effectively lengthen the underground portion of the stem thus increasing yield. You can either add additional soil to the bed and then mound it around the plants, or you can scoop up soil from the rows and press it against the stems. Later in the season, it’s easy to reach in and check the potatoes for size before you harvest them. After the plants reach about 20 to 30cm tall, soil needs to be hilled around the plants for the potato tubers to grow in. These “hills” or ridges are where the potatoes will form, and it is important to keep them covered and away from sunlight. If the potato tubers come in contact with sunlight they can become green and not fit to eat. In fact, green potatoes can carry toxins and could become poisonous. To prevent this, potatoes should be hilled at least 3 to 4 times during their growth cycle. The more you can hill t

Complete Guide To Chicken Feed Formulation

The common ingredients are whole maize, maize bran, cotton seed cake, soya beans, sunflower and fishmeal (omena). In addition, farmers need to add several feed additives (micronutrients, minerals and vitamins) to ensure their birds have a balanced feed that meets their daily nutrient requirements. Ingredients are cheaply available, especially after the harvesting season. Depending on the cost of ingredients, farmers who make their own feeds at home save between 30 to 50% for every 70kg bag of chicken feed, depending on the source of their raw materials. Due to government regulation, major feed companies have reduced the standard quantity of feed from 70kg to 50kg per bag, but the price of feed still remains almost the same. This means that farmers who are able to make their own feeds make great savings on feeds which take up to 80% of the production costs. To formulate feed, farmers have to use the Pearson Square Method . In this method, the Digestible Crude Protein (DCP) is
